Sample Solution:

C# Sharp Code:

using System;

// Class definition named 'funcexer8'
class funcexer8
{
    // Method to calculate the Fibonacci series up to 'nno' numbers
    public static int Fibo(int nno)
    {
        int num1 = 0;
        int num2 = 1;

        // Loop to calculate Fibonacci series
        for (int i = 0; i < nno; i++)
        {
            int temp = num1;
            num1 = num2;
            num2 = temp + num2;
        }
        return num1; // Return the Fibonacci number
    }

    // Main method, the entry point of the program
    public static void Main()
    {
        // Display a description of the program
        Console.Write("\n\nFunction : To display the n number Fibonacci series :\n");
        Console.Write("------------------------------------------------------------\n");

        // Prompt the user to input the number of Fibonacci Series
        Console.Write("Input number of Fibonacci Series : ");
        int n = Convert.ToInt32(Console.ReadLine());

        Console.WriteLine("The Fibonacci series of " + n + " numbers is :");
        // Loop to print the Fibonacci series up to 'n' numbers
        for (int i = 0; i < n; i++)
        {
            Console.Write(Fibo(i) + "  "); // Call the 'Fibo' method to calculate and display each Fibonacci number
        }
        Console.WriteLine(); // Move to the next line after displaying the series
    }
}

Sample Output:

Function : To display the n number Fibonacci series :                                                         
------------------------------------------------------------                                                  
Input number of Fibonacci Series : 10                                                                         
The Fibonacci series of 10 numbers is :                                                                       
0  1  1  2  3  5  8  13  21  34
